Need some technician to implement the code of creating chat groups in instagram with web http request.

I am looking for a skilled technician who can help me implement the code for creating chat groups in Instagram using web HTTP requests. I do not have the code and will need the freelancer to provide it, or give the detailed way to make it, preferably in C#, but other language is also OK as long as you can make it work. There are no specific requirements or features for the chat groups, so I am open to suggestions.

Skills and experience needed:
- Proficiency in programming language
- Experience with web HTTP requests
- Knowledge of Instagram's chat group functionality
